WebP is the recommended image format for the modern web. Developed by Google, it uses advanced compression from the VP8 video codec to produce files 25-34% smaller than JPEG at equivalent quality, with full transparency support.

Pikkx converts images to WebP entirely in your browser using jSquash WebAssembly codecs. The conversion happens on your device — your images are never uploaded to any server. Drop your files in, adjust quality, and download optimized WebP images in seconds.

Frequently Asked Questions

WebP is a modern image format developed by Google. It produces files 25-34% smaller than JPEG and 26% smaller than PNG at equivalent visual quality. It supports transparency and animation, and has 97%+ global browser support in 2026.
Will WebP images work in all browsers?+
Yes, for almost all users. WebP has over 97% global browser support as of 2026. The only browser that doesn't support it is Internet Explorer, which was discontinued in 2022.
Does converting to WebP reduce quality?+
WebP supports both lossy and lossless compression. At quality 80, lossy WebP is visually identical to the original JPEG or PNG at a significantly smaller file size. You can adjust the quality slider to find the right balance.
Can I convert WebP with transparency?+
